Measuring the Business Performance
Net Income (NI) = Revenues (R) –
Expenses (E)
Revenues: the price of products, 
merchandise, and services supplied by a 
firm to its customers during a certain 
period
Expenses: the cost of products, 
merchandise, and services used by a firm 
during a certain period 
by Nguyen Bao Linh
Methods of Recognition
The accrual basic recognizes the impacts 
of transactions on the financial 
statements when revenues and expenses 
occur regardless whether cash changes 
hands 
The cash basis only records transactions 
when cash is disbursed or received

Accounting Period
To periodically provide information to 
users, the firm’s operating process is 
allotted into relatively equal period, 
called accounting period
The length of an accounting period may 
be a month, a quarter, or a year. One-
year length is called a fiscal year
by Nguyen Bao Linh
Accounting Period
A fiscal year is not necessarily a calendar 
year. The end of a fiscal year may not 
coincide with the harvest in order to 
– Lessen the accountant’s work at the end of 
the period 
– Simplify the inventory work 
– Reduce the workload of allocating revenues 
and expenses over various periods to account 
profits accurately

Permanent and Temporary Accounts
A temporary account is the one that will 
be closed (its balance equals zero) at the 
end of the accounting period to be 
prepared for recording in the next 
period 
A permanent account is not closed at the 
end of period; its ending balance 
becomes the beginning one for the next 
period

Matching Rule
Revenues are recognized in an accounting 
period during which the firm provides 
products, merchandise, and services to 
customers 
Expenses that are recognized in an 
accounting period must been used up 
during that period to generate the period 
revenues 
by Nguyen Bao Linh
Going-concern Rule
Firms are assumed to be continuously and 
indefinitely operating unless there is 
evidence on bankruptcy or stopping 
business 
This assumption allows accountants to 
simplify their calculation and allocation of 
revenues and expenses over more than 
one period such as
– Deferred Revenue
– Depreciation of Fixed Assets

Revenue Recognition
Revenues are recognized when goods and/or 
services are delivered to customers regardless 
whether collections have been made 
To secure the matching rule, revenues are also 
recorded by adjusting accounts at the end of the 
accounting period

Receivables

involve in products, merchandise, or services that 
have been used to generate the period revenues, 
regardless whether cash changes hands
